It's not actually about time. It's always about priority. We "don't have time" to coach an employee, reorganise our divisions, plan team development, play with our children, exercise, or date our spouses. It's not because we don't have time. It's because we give these activities lower priorities than other tasks. That is a sobering thought. "I have these three meetings scheduled. They are more important to me than helping my subordinate plan his career development". "I need to make sure this proposal is perfect so that I can send it out first thing Monday. It is more important to me than bringing my family to the camping trip".
No one has time. Whenever we are asked to do something extra, we feel overwhelmed and that we can never find time for it.
Yet everyone has time. It's just about what you have chosen to do with it.
